Try It: Solving
To practice identifying absolute value equations with no solution, solve the equation . Begin by isolating the absolute value expression by subtracting from both sides, which yields . Because the distance represented by an absolute value must be positive or zero, it can never equal a negative number. Thus, observing that the isolated absolute value is equal to immediately indicates that there is no solution to the equation.
